Idk what the hell is happening to my family’s dog. We took him to the vet and they got a sample which they said is non-cancerous but the bumps are just growing bigger. Has anyone ever dealt with this? They said the bumps are due to trauma but the only thing that could count as trauma is our other dog playing too roughly with him, and our other dog is much smaller than him. They normally jump around and on each other but the smaller one’s only 50 pounds and this big guy is 90 pounds.
